Safety information
Classification of the safety information
WARNING!
The WARNING! safety indication refers to a risk of personal injury.
CAUTION!
The CAUTION! safety indication refers to a risk of damage to property.
ATTENTION!
The ATTENTION! safety indication refers to a risk which can cause
equipment to become unserviceable.
IMPORTANT!
The IMPORTANT! designation indicates application information and
other particularly important information.
Knowledge of the User Manual
80116-287 
2018-09
The user manuals relating to the units form part of this service manual. Familiarity with the user manuals, in particular the procedures for setting up,
commissioning and handling described in the manuals, is a prerequisite for
the performance of servicing work.
Protection from the risk of electric shock
WARNING!
The supply voltage must match the voltage specified on the rating
plate. Connect the unit / the equipment cart to a properly installed
grounded outlet. Only use the Erbe power cord or an equivalent power
cord for this purpose. The power cord must bear the national test symbol.
For safety reasons, multiple outlets and extension cords should not be
used. If their use is unavoidable, they also must be provided with proper
grounding.
WARNING!
Unplug the power cord from the outlet before exchanging parts of the
unit or cleaning it.
WARNING!
Do not plug a wet power cord into the unit or into an outlet.
7 / 84
1 • Safety information
WARNING!
Do not touch any unprotected wires or conductive surfaces while the
unit is opened and under voltage.
WARNING!
Blown line fuses may only be replaced by a competent technician. Only
replacement fuses of the rating specified on the unit's name plate may
be used. Before resuming operation the unit must be subjected to a
performance test by a competent technician.
Electrostatically sensitive components
CAUTION!
This unit contains electrostatically sensitive components. Work at an
anti-static workplace while repairing the unit. Wear a grounding armband while working with electrostatically sensitive components. Hold
the circuit boards by their non-conducting corners. Use an anti-static
container for transporting electrostatically sensitive components and
the circuit boards.
ATTENTION!
Adjustments, tests, modifications, maintenance and repair work may
only be performed by Erbe or persons trained by Erbe. If the work is not
performed by trained persons, Erbe accepts no liability and warranty
rights become void.
It is recommended that the technical safety check also be performed by
Erbe or persons trained by Erbe.
ATTENTION!
8 / 84
Only use original Erbe spare parts. The manufacturer accepts no liability
and the warranty rights becomes void if original spare parts are not
used.

CHAPTER 7
Maintenance and servicing
Who is allowed to perform servicing and maintenance
work?
ATTENTION!
Adjustments, tests, modifications, maintenance and repair work may
only be performed by Erbe or persons trained by Erbe. If the work is not
performed by trained persons, Erbe accepts no liability and warranty
rights become void.
It is recommended that the technical safety check also be performed by
Erbe or persons trained by Erbe.
What is a technical safety check?
80116-287 
2018-09
IMPORTANT!
The technical safety check is a preventive measure to examine whether
the device is safe and ready for operation. In order to perform the various tests the current specifications and regulations of the particular
country and the instructions in this service manual must be observed.
How often does a technical safety check have to be
performed?
IMPORTANT!
A technical safety check must be performed every time after maintenance, but at least once per year.
51 / 84
7 • Maintenance and servicing
Technical safety check – step by step
For simplification the device to be tested is referred to below as the "test
specimen".
Safety information
52 / 84
For safety reasons (personnel protection) the test specimen should
generally be operated by a suitable isolating transformer. 
An exceptional case is the tests for grounded conductor resistance,
ground leakage current, and patient leakage current, in which the test
specimen is supplied with current via the safety tester.
ATTENTION!
In the event of a fault occurring in the test specimen or individual components during the technical safety check the test steps taken so far no
longer apply. 
Remedy the defect and repeat the technical safety check from the
beginning.
ATTENTION!
The specifications made in this chapter for test programs / test program settings allow the service technician to perform the technical
safety check. In addition, the test program mode provides a number of
diagnostic and inspection options for the service technician. They are
described in the repair manual. Erbe Elektromedizin expressly states
that the full functional range of the test program mode may not be
used without precise knowledge of the individual test programs.
IMPORTANT!
It is assumed that the user knows how to operate the test specimen,
the test equipment, the measuring equipment, and auxiliary test equipment. The test instructions only apply in conjunction with the relevant
test steps.
IMPORTANT!
Test equipment, measuring equipment, and auxiliary test equipment
(cables, test boxes, etc.) are listed separately at the beginning of each
test unit. Where Erbe article numbers are specified, only original Erbe
test equipment, measuring equipment, and auxiliary test equipment
may be used.
IMPORTANT!
The test report for the technical safety check can be requested from
Erbe Technical Service Tübingen. For the address see address sheet on
last page.

2 seconds an acoustic warning must be emitted. The test specimen
must interrupt activation.

• The test specimen is connected to the power supply via the power
cord.
• The NE socket of the test specimen is connected to the VIO Testbox via
the patient cable NE with the adapter cable.
• The AE socket of the test specimen is connected to the VIO test box via
the patient cable AE and the electrode handle with the laboratory
measuring cable.

WARNING!
Test setup
Across the measuring lines there is the DC voltage of 500 V! In order to
avoid injuries, only switch on the test specimen and safety tester when
all the electrical connections have been made.

• The power cord connects the VIO 300 D to the power supply.
• The VIO 300 D is switched off.
• The bipolar resection adapter is connected to the MF socket of the
VIO 300 D.
• The bipolar resection adapter is connected to the safety tester (measuring input for insulation testing) via the measuring cable.
Test procedure
1. Switch the VIO 300 D on.
2. Start insulation testing. A charging current briefly flows via the
decoupling capacitor. A resistance > 200 MOhm must then be displayed.

• The test setup is configured as illustrated above. IMPORTANT! The test
is carried out without a connected load.
• The power cord connects the VIO 300 D to the power supply.
• The bipolar resection adapter is connected to the MF socket of the
VIO 300 D.
• The dual-pedal footswitch with ReMode is connected.
Test procedure
1. Call up Setup level 2 (see page 20).
2. Select the "Test programs" setting.
3. Use the Up button to select "Hardware TP" and press Enter to confirm. The test specimen switches to the test program mode.
4. Use the Up/Down buttons to select the "TP generator" test program
and press Enter to call it up.
5. Perform the following settings in the test program:

– Test mode: AUTO
– Output socket: 3 BIPOLAR (3 = sockets slot, BIPOLAR = arrangement with multifuction socket, to which the bipolar resection
adapter is connected)
6. Use the footswitch to activate the VIO 300 D.
7. Use the oscilloscope to determine the peak value of the HF output
voltage.
8. Determine the measured voltage V UpHF in the test program.
9. Calculate the transfer ratio. 
tr = UOscilloscope / UV UpHF
The value determined must lie between 0.36 and 0.44.
10. Remain in the Test program.

1. Set HF power meter to:
RL = 50 ohms
2. Keep the previous settings in the "TP generator" test program:
– Test mode: AUTO
– Output socket: 3 BIPOLAR (3 = sockets slot, BIPOLAR = arrangement with multifuction socket, to which the bipolar resection
adapter is connected)
3. Use the footswitch to activate the VIO 300 D.
4. Determine the power delivered on the HF power meter. The value
must be > 100 watts.
